Weird Shape form in Civil Connection

Processing: 1.pkt…
I have try the Civil Connection Dynamo with [01]Model_Create loft with sample lines_Shapes_2.0_DP.dyn
Script to form a tunnel model as shown.


In the Revit , it gave me the correct Left Side but a Strange Right Side.

How can i edit the sub-assembly to fulfil the Civil connection requirement.(In this case , i used - anti-clockwise order with “Point Code”)
